BACKGROUND OF THE INVENTION

Video games are a major genre of entertainment. There is a growingmarket for games, gaming leagues and news stories. In this regard,techniques have arisen to document and record the happenings and events.Methods to enable recording of video games into movies include thefollowing:

1. A software module grabs shots of the screen, and sound data from asound card, to save them as frames in a movie (see FIG. 1); or

2. A hardware capture device is hooked between a game console and ascreen or a PC and a screen, and the hardware capture device places thestream into a PC or other device for recoding as a movie (see FIG. 2).

Of note, video games are typically played either on a personal computeror on a dedicated game console. The term “game device” may sometimes beused herein to refer either to a game console or a personal computer onwhich games are played. A game device is typically connected to a 2Dscreen. To record the games into movies, a recording module may grabshots of the screen and save them as frames in a movie. The recordingmodule would also query the sound card driver iteratively to get datarelated to the currently played sound (see FIG. 1, showing game device101, game 103, graphic engine 105, audio engine 107, video card 109,audio card 111, recoding module 113 and movie file 115).

In the case where the recording is performed on a separate computer ordevice that is not the game device, the cable output of the game devicemay be connected to a capture device which reroutes the frames into thecomputer. This computer captures the frames and the audio (e.g., severaltimes a second) and saves the frames and audio data into a movie. Thecapture device could be installed as part of the computer, as a videocapture card or be a separate device altogether. The computer istypically a personal computer but could also be a device with InternetProtocol Broadcasting capabilities (see FIG. 2, showing game device 201,monitor 203, capture device 205, computer 207, recoding module 209 andmovie file 211).

DETAILED DESCRIPTION OF THE INVENTION

Detailed embodiments of the present invention are disclosed herein;however, it is to be understood that the disclosed embodiments aremerely illustrative of the invention that may be embodied in variousforms. In addition, each of the examples given in connection with thevarious embodiments of the invention is intended to be illustrative, andnot restrictive. Further, the figures are not necessarily to scale, somefeatures may be exaggerated to show details of particular components(and any data, size, material and similar details shown in the figuresare, of course, intended to be illustrative and not restrictive).Therefore, specific structural and functional details disclosed hereinare not to be interpreted as limiting, but merely as a representativebasis for teaching one skilled in the art to variously employ thepresent invention.

In one embodiment of the present invention a mechanism (e.g., softwareand/or hardware) may be provided to broadcast video games and/or movieslive. In this regard, as video games become similar to sports, livevideo game broadcasting may be important for several usages, including,but not limited to:

1. Enabling users to share with friends their experience essentiallywithout delay

2. Live, essentially no delay news feeds from virtual worlds events

3. Assistance to players during games and virtual battles

4. Communication between team players during games

In one embodiment of the present invention a mechanism (e.g., softwareand/or hardware) may be introduced before, after or instead of aconventional movie saving module. Instead of (or in addition to) savingthe movie to a file, various embodiments of the present invention mayprovide for a live broadcasting module (e.g., the video frames of thegame may be encoded using a movie encoder such as, for example, h264,h263, and/or other encoder which is aimed at reducing frame size). Theaudio may be encoded and interleaved into the movie, for example, usingindustry-standard encoders such as AAC, MP3 and/or any othercompressors. The game may then be broadcast as a stream of frames, usingInternet Broadcasting Protocols such as, for example, RTSP, RTP, UDP,TCP/IP and/or others. At the receiving side, standard and/or proprietarymethods could be used to view the live broadcast. In various examples,the game broadcast could either go directly to another computer, or to astreaming server which broadcasts it to several receiving clients. Atthe receiving side, a receiver may translate the byte stream into frameswhich are decoded into frames. In one example, the receiver and decodercan work as one integrated module.

One example describing the steps to broadcast live from video games isas follows:

-   -   1. A software driver obtains shots of the screen from computer        memory (e.g., directly from computer memory)    -   2. The software driver places the obtained shots of the screen        in a driver memory    -   3. A software module is connected to the driver memory    -   4. The software module encodes the frames from the driver memory    -   5. The software broadcasts the frames using Internet protocol(s)

With reference now to FIG. 3, it is seen that one embodiment of thepresent invention utilizes the following: game device 301, game 303,graphic engine 305, audio engine 307, video card 309, audio card 311,recoding module 313 (of note, in this example recording may be enabledand the “recording module” may operate to enable both recording and livebroadcasting; when recording is not enabled, the “recording module” 313would operate to enable live broadcasting only), Internet 317, receivercomputer(s) 319, IP receiver 321, decoder 323 and monitor 325).

In the case where a separate computer is doing the broadcasting, thecable output of the game device may be connected to a device whichreroutes the frames into this broadcast computer. The frames may betransferred into the broadcast computer using (for example) a hardwareport, a software driver may read the frames and put them in drivermemory and from that point the broadcasting may be performed (see FIG.4, showing game device 401, monitor 403, capture device, 405, computer407, recoding module 409 (again, of note, in this example recording maybe enabled and the “recording module” may operate to enable bothrecording and live broadcasting; when recording is not enabled, the“recording module” 313 would operate to enable live broadcasting only),encoder and IP broadcaster 415, Internet 417, receiver computer(s) 419,IP receiver 421, decoder 423 and monitor 425).

Of note, the broadcasting “computer” could be any device with, forexample, Internet Protocol Broadcasting capabilities.

Reference will now be made to a detailed example of a video gameimplementation of an Encoder and IP Broadcasting Module as an InstantMessenger (sometimes referred to herein as “IM”). Video games typicallypresent their visual by iteratively calculating positions of theirentities and then drawing them on the screen. This process happenstypically 20 times per seconds (and optimally more). The drawing of thescreen is typically done by a special video card which receives thepositions of the entities (in 2D or 3D space coordinates), their shapesand textures, and converts the information into a 2D picture by a set ofmathematical transformations. The 2D picture is typically stored at ascreen buffer which is presented at the 2D monitor that is used todisplay the game. The games typically include a graphic engine toconnect to the video card, such as (for example) DirectX or OpenGL (seeFIG. 5, showing that: game 501 may provide output to graphic engine 503,which may provide output to video card 505, which may provide output tomonitor 507).

A video game's audio, much like any other computerized audio, typicallyworks by encoding sounds as byte data and sending them to the soundcard.

To broadcast the game live, a software module according to an embodimentof the present invention needs to capture the 2D screen buffer and theaudio. To capture the screen buffer, after the graphic engine calls thevideo card driver to render the screen, a call may be made to theRecording Module. The Recording Module may call the video card and copythe screen buffer to its own buffer. This buffer may then be passed toan Encoder and IP Broadcaster module. The Encoder and IP Broadcastermodule may run (for example) in a separate memory address space, so thepassing of the buffer may need to be done through a shared memory. Forexample, the Encoder and IP Broadcaster module could be an InstantMessenger application. This Instant Messenger (IM) may operate byquerying a virtual camera driver, written specially to hold and pass thedata from the Recording Module to the Instant Messenger. This may beperformed several times a second, in order to broadcast an animatedmovie, live.

To capture and broadcast the audio, a module according to an embodimentof the present invention may query the audio card driver, for example,several times a second—each time bringing back sound data. This may bedone via a software layer such as, for example, WASAPI in Windows Vista,or via other drivers of the audio card, that supply channels to receivethe audio. If an IM is used to broadcast the game, the IM may use avirtual microphone driver to obtain the audio. This means that the IMmay select a special microphone that is not connected to an externalmicrophone (and not bringing audio from an external hardwaremicrophone), but is connected to the recording module of the audiobringing audio from the game (see FIG. 6, showing that one embodiment ofthe present invention utilizes the following: game device 601, game 603,graphic engine 605, audio engine 607, video card 609, audio card 611,recoding module 613 (of note, in this example recording may be enabledand the “recording module” may operate to enable both recording and livebroadcasting; when recording is not enabled, the “recording module” 613would operate to enable live broadcasting only), virtual webcam 614,virtual microphone 616, IM 618, Internet 617 and monitor 625).

Of note, the broadcasting could be done by any desired module and notonly an Instant Messenger. For example, many Internet browsers haveplug-ins such as Flash, that allows them to connect to a microphone anda camera. In addition, a dedicated broadcasting module could skip theneed for a web cam and a virtual microphone driver, and interfacedirectly with the recording module.

The recording module may connect between the graphic engine and thevideo card driver, but could (in another example) be connected directlyto the game. Additionally, the broadcasting could be performed from acomputer or device which is separate from the game device. In this case,a cable splitter may reroute game device output to a capture device andthe broadcasting device, as depicted in FIG. 4, for example.

Reference will now be made to an example of interleaving (or mixing)audio and video. Under this example, there are three main components(modules) that are involved:

(1) Audio capturer (see, e.g., audio capturer module 1001 of FIG. 10),the module that captures the audio from the external or internal audiodevice. This audio capturer module interfaces with an audio devicedriver, captures the audio and outputs the audio as “audio packet” data.In this example, the number of audio packets and their size is relatedto the capturing frequency and requested quality.

(2) Video capturer (see, e.g., video capturer module 1003 of FIG. 10),the module that captures the video from the screen or camera. This videocapturer module interfaces with the screen driver, captures the screenimages, and outputs the video as “video packet” data. In this example,the number of video packets and their size is related to the capturingfrequency and screen size.

(3) Broadcaster (see, e.g., broadcaster module 1005 of FIG. 10) is themodule that receives the audio and video packets, interleaves (or mixes)the audio and video packets together, and broadcasts the interleavedaudio and video packets as data packets (e.g., over the Internet). Inthis example, the format of the data packets and their order are definedby the desired broadcasting protocol (e.g., RTMP, RTP, proprietary).

Still referring to this example, the interleaving (or mixing) may becarried out iteratively at each of a plurality of time steps. In thisexample, at each time step the various modules perform processing asfollows:

1. Audio capturer (see FIG. 10):

-   -   a. Capture audio packet (using a process/mechanism described        elsewhere herein)    -   b. Timestamp the packet    -   c. Add packet to a queue    -   d. Add packet length (in time units) to an audio time length        variable

2. Video capturer (see FIG. 10):

-   -   a. Capture video packet (using a process/mechanism described        elsewhere herein)    -   b. Timestamp the packet    -   c. Add packet to a queue

3. Broadcaster (algorithm example 1—see FIG. 10):

-   -   a. Take first and second video packet    -   b. Encode video packets    -   c. Send first video packet    -   d. Loop on audio packets queue from less recent to most recent.        For every audio packet:        -   i. encode audio packet        -   ii. If            first_video_packet.timestamp−audio_packet.timestamp>epsilon            then discard audio packet (since audio packet is too old)        -   iii. If second_video_packet.timestamp>audio_packet.timestamp            then send audio packet (in this example, epsilon for bullet            points ii. and iii. is defined empirically, and would            typically be around 100 ms)        -   iv. send remaining audio packets and video packet

In another example variant on the interleaving (or mixing) algorithm,the Broadcaster may operate as follows:

3. Broadcaster (algorithm example 2—see FIG. 10)

-   -   a. Take first and second video packet    -   b. Encode video packets    -   c. Send first video packet    -   d. If        |first_video_packet.timestamp−second_video_packet.timestamp|>audio        time length variable then        -   i. Loop on all audio packets. Expand each audio packet by            |first_video_packet.timestamp−second_video_packet.timestamp|/(audio            time length)    -   e. If        |first_video_packet.timestamp−second_video_packet.timestamp|<audio        time length variable then        -   i. Loop on all audio packets. Shrink each audio packet by            (audio time length)/|first_video_packet.timestamp−second            video_packet.timestamp|    -   f. send audio packets and video packet

In this example, shrinking audio packets is done by:

-   -   1. Loop on all bytes in audio packet    -   2. delete every X byte, where X is (audio time        length)/|first_video_packet.timestamp−second_video_packet.timestamp|

In this example, expanding audio packets is done by:

-   -   1. Loop on all bytes in audio packet    -   2. duplicate every X byte, where X is        |first_video_packet.timestamp−second        video_packet.timestamp|/(audio time length)

In another example, packets may be taken from the front of the queue(s)and input into the interleaving algorithm.

Referring now to FIG. 13, another embodiment of the present invention isshown (as seen in this FIG. 13, this embodiment relates to gamebroadcasting using an application comprising a DLL and an EXE).

More particularly, a mechanism for game broadcasting according to thisembodiment may be carried out as follows (of note, the motivation to docode insertion, as described in steps 4 and 5, is because using othermethods of grabbing the screen can produce errors, like black screens,incomplete drawn screens and others, thus essentially rendering suchother methods useless):

-   -   1. As mentioned above, the application according to this        embodiment comprises an EXE and a DLL (see, e.g., DLL 1301        (sometimes referred to as “Hook DLL”) and EXE 1303 of FIG. 13)    -   2. The DLL 1301 registers itself at the operating system to        receive messages upon events happening at other programs (this        is called hooking) Specifically, the DLL 1301 in this example        will take action when:        -   1. a window is created or receives focus and/or        -   2. some keyboard keys are pressed (e.g., predefined keys            combinations)    -   3. A game (see, e.g., Game 1305 of FIG. 13) starts, creates a        window and this window receives focus    -   4. The Hook DLL 1301 is loaded into and called in the context of        the game process memory space    -   5. When Hook DLL 1301 is called, Hook DLL 1301 identifies: (a)        whether this is a game; and (2) what version of graphics engine        (e.g., DirectX/OpenGL—see, e.g., DirectX/OpenGL drivers 1306))        does the game use. If it is a game with detectable graphics        engine, Hook DLL 1301 inserts code that reroutes the main        drawing methods function into the Hook DLL's own replacement        method. In this example, the code insertion is done by the        following sub-steps:        -   1. The Hook DLL 1301 calculates the memory address of the            main drawing methods of the graphics engine        -   2. The Hook DLL 1301 replaces the first original bytes of            each method with bytes that represent an instruction to jump            to the DLL's own replacement method. This will reroute any            executing program that reaches those bytes, to the Hook            DLL's own replacement methods        -   3. The Hook DLL's replacement method can now perform tasks            like, for example, capturing the screen, presenting graphics            and more (detailed below)        -   4. The Hook DLL 1301 also would call the engine's original            drawing method, so the functionality of the game will remain            the same    -   6. The EXE 1303 opens a window with user interface elements        (e.g., buttons) for Start/Stop broadcasting, and for settings        configuration    -   7. The DLL 1301 presents some graphic user interface on the        screen, layered on top of the game. The layered graphic user        interface may include (but not be limited to), for example:        company logo, statistics (e.g., frame rate, time), hot key        instructions (e.g., “press Ctrl+F1 to start”), etc    -   8. When a predefined keys combination is pressed, or when the UI        button is pressed to Start Broadcasting, the following starts to        happen in a loop (the frequency of which depends (in this        example) on the game frame rate and the game device        capabilities):        -   1. The DLL 1301:            -   1. captures the video from the screen buffer (see, e.g.,                video card 1307A and screen buffer 1307B of FIG. 13),            -   2. puts the captured video in a shared memory area (see,                e.g., shared memory 1309 of FIG. 13)            -   3. sends a notification to the EXE 1303        -   2.
